HEATING UNIT.

Application ma April 7, 1923. Serial No. 630,617.

My invention belongs to that general class of devices known as heating apparatus, and relates particularly to a heating unit adapted to be used in shops, factories, garages, storage warehouses and such other places as the same may be applicable.

The invention has among its objects the production of a device of the kind described that is simple,'compact, convenient, of light weight, durable, efiicient and satisfactory, and which may be installed at'any desired point. More particularly it has as an object the production of an eflicient, inexpensive and light weight unit, which may be attached to a wall or suspended or mounted on a suitable base, and which will have great capacity. It also has among its further objects the production of a device in which a circulator is employed which may be motor driven and in which the motor is entirely. out of the current of heated air, whereby the same will not overheat even though not enclosed, and, as a matter of fact, which will, if anythin be maintained cool.

Many ot er objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosures herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference 'characters indicate like or corresponding part-s:

Fig. 2 is an enlarged sectional view illustrating the details of construction;

Fig. 3 is a sectional view taken substantially on the line 3--3 of Fig. 1;

Fig. 4 is a side elevation of the same with a portion broken away;.

Fig. 5 is a sectional view taken substantially on the line 55 of 3;

Fig. 7 is a front elevation of the same;

Fig. 8 is a partial sectional view illustrating another modified form of device; and

Fig. 9 is a front elevation of the device shown in Fig. 8.

In the drawings, wherein I have illustrated the preferred embodiment of my in- At some suitable point the unit is provided with an inlet 3 for the heatin medium and at another point it is provide with an outlet 4 for the condensation products from the heating medium. Bars 5 are inserted through the adjacent ends of the heating elements 1 for securing them together. The entire unit may be attached to a wall or suspended or mounted on a suitable base, in the present instance hanger rods 6 are secured at one end to said unit and at the other end to a suitable support. Extending about the perimeter of the unit is a casing 7, the same extendin to one side thereof and taper-in so as to ecrease in area toward its free en In order to increase the heating capacity of the unit a circulator may be used, as for instance a fan 8 spaced from the unit and arranged at the discharge end of the casing 7 and driven by a motor or the like 9, ar-

ranged at the opposite side of the unit, said motor and fan having a shaft 10 drivingly connecting-them.

In order to provide a suitable bearing for the shaft and a'support for the motor, one of the heating elements, as for instance, the central member 11 is formed without the tubular portion connecting its sides, but carries brackets 12 and 13 lntegral therewith and extending in opposite directions, one of said brackets 12 providing a support for the motor 9 and the other bracket 13 having an aperture 14 therethrough forming a bearing for the shaft 10. An additional bearing 15 in line with the bearing 14 may be provlded on the bracket 12 adjacent the motor support, if so desired.

A similar construction is shown in Figs. 6 and 7 in which case, however, I have shown the heating unit as consisting of substantially two assembled units or elements, which may be similar to the well-known type of automobile or like radiator. This type of unit generally is very efiicient and of light weight.

Referring to the figures, 20 re resents a suitable base plate, in the parti'cu ar' device shown a channel, provided with the side flanges 21.

suitably 23 PI'O]6CtiI1g through the plate and carry- Plate 20 carries a bracket 22 secured theretoand having. a part ing a bearing for the fan shaft.

' I have shown a motor 24shaving a fan shaft 25 extending as'shownand provided with the desired number of fan blades 26. Obviously any suitable fan and driving mechanism maybe employed for the purpose. The heating u'nitsinthis case are indicated by the characters 27-, the same representing substantially any of the well-known types of automobile radiator constructions.

These are secured at either side of the base plate and communicate with the tanks or chambered ends or receptacles 28 and 29, which may be connected by the side pieces 28.

I have shownports at the top and bottom for the admission and discharge of the heating medium, such as hot water, steam or the like. The upper port 31 is in a chambered part provided with. connecting parts 30 communicating with the tank 28, while the lower port 33 is provided in a similar part having communicating vducts 32 connecting'with the tank 29. A casing or shell 35 is soarranged about and enclosing the discharge end of the heating unit that the air is drawn to and through the unit, heated and discharged through the outlet end 36.

similar to that previously described.

With the arrangement shown, whereby the fan is on one side of the heating unit and the motor on the other side, it will be noted that the motor is entirely out of the current of heated air so that the same will not be overheated, eventhough it is not enclosed, but on the contrary it will be mai-ntainedcool because the suction of the fan 8 will cause the cool air to be drawn past the motor and heating elements and be discharged outwardly of the casing.

In the form shown in Figs. 8 and 9 thedevice is similar to that previously described in Figs. 6 and 7, except that in this instance the motor and fan are arranged on the same side of the heating unit, whereby the overall depth of the device is materially lessened and the danger of unauthorized tampering with the motor is obviated to a large degree. In this form the bracket 23 is adapted to be held to the part 20 by any suitable means, as for instance by bolts 42. A shield 40 is arranged to surround the motor 24:, and the part 20 is provided with apertures 41 therethro gh, whereby the cool air is drawn therethrough past the motor by the fan, thereby I cooling the motor and increasing its eficiency of-opera'tion. 1

7 Having thus described my invention it is obvious that various immaterial modifica: tions maybe made in the same without dcparting from the spirit of my invention;

hence I do not wish to be understood as'limitingmyself to the exact form, arrangement,

construction and combination of parts hereii -shown and described or uses mentioned.

- What I claim as new and desire to secure by Letters Patent is I 1. In a. device of the kind described and in combination, a heating unit formed of aseries of adjoined heating elements, a fan on one side of said unit and a motor on the other side thereof, one of said elements'having a.

motor support formed integral therewith.

2. In a device of the kind described and in combination, a heating unit formed of a series of adjoined heatin on one side of said unit nd a motor on the elements, a fan other side thereof, one of said elements having a motor support formed integral there- T with and having apertures therethrough to= provide bearings for the fan shaft.- -3. In a device of the kind described and in combination, a heating unit formed of a series of adjoined heating elements, .a cas ing around sai'd unit and extending therefrom, a fan-in said casing, a motor on the opposite side of said unit and a shaft co'nnecting said motor and fan,- orie of said heat ing elements having a bracket integrally formed thereon and extending on opposite sides thereof to support said motor and provided' with apertures to form bearings for the fan shaft.

4. Ina device of the class described and in combination, a plurality of heating elements, means for suspending said elements in a vertical plane from a ceiling or the like, 1

a bracket supported between the upper and 5. Ina device of the class described and- 1n comb1nat1on,a plurality of heating'ele'- ments, means for suspending said elements 1n a verticalv plane from a ceiling or the lower ends of the elements, a motor and I like, abracket supported between the up per and lower ends of the elements, a motor and shaft therefor supported upon the bracketin a horizontal plane, said motor being positioned upon one side of the heating elements, a fan at the outer end of the shaft arranged on the other side of the ele- I ments', and a casing carried by the elements and tapering to a restricted outlet at the outer end of the shaft with the fan arranged in said outlet. g

In testimony whereof, I have hereunto signed my name.
